Heidelberg Catechism Week 12

31. Q. Why is He called "Christ," meaning "Anointed"? A. Because He has been ordained by God the Father and has been anointed with the Holy Spirit to be our chief prophet and teacher who perfectly reveals to us the secret counsel and will of God for our deliverance; our only high priest who has set us free by the one sacrifice of His body and who continually pleads our cause with the Father; and our eternal king who governs us by His Word and Spirit, and who guards us and keeps us in the freedom He has won for us.

32. Q. But why are you called a Christian? A. Because by faith I am a member of Christ and so I share in His anointing. I am anointed to confess His name, to present myself to Him as a living sacrifice of thanks, to strive with a good conscience against sin and the devil in this life, and afterward to reign with Christ over all creation for all eternity.

My reflections on the reading from the book...

Christ was anointed to three offices, those of prophet, priest, and king. 

Prophet... 

"[Christ] is the one and only who makes known the Father (John 1:18) and revels the exact nature of God. As a prophet Christ came to show us the way and declare the will of God... [and] to fulfill it, and He laid down His life, not just an example of the way of God but as the way to God."

Priest...

"The only priest we need is Jesus Christ because His sacrifice on the cross was the end of the sacrificial system. High priests served two related functions - making atonement and making intercession for the people - both of which are accomplished for us in Christ. Christ died for us (once for all, never to die again), and Christ prays for us (continually and repeatedly)."

King... 

"As a king, Christ does two things: He governs and guards... Christ governs us by Word, to give us a propositional revelation of His will and an objective set of external truths, and by Spirit, to give us a subjective experience of His presence and the inner power to obey... He will not let us fall to the Devil (not ultimately), and He will not let us offer ourselves again to the world's bondage (not finally). He loves us and the freedom He purchased on our behalf."

The 32nd question/answer uses the same language to describe our role as Christians: "As little Christs, ordained by the same Father and anointed by the same Spirit, we are to fulfill, in a lesser way, the same offices as our namesake. We confess His name like good prophets, present ourselves as living sacrifices like good priests, and fight our mutual enemies and reign in joint dominion like good kings."
